What are 4D number Plates?
Lets first look at what a 4D number plate is. A 4D number plate, in summary, is a number plate that is made up of the usual components that a standard number plate is made up of but with the added extra of protruding acrylic digits on the surface of the number plate.
These protruding digits, or characters, are secured to the surface of the number plate acrylic with double sided tape or silicone; here at JDM Plates we use industry standard 3M double sided tape. Our adhesive tape comprises high adhesion characteristics with high temperature and UV stability; our selected tape was designed to be made for outdoor use on point of sale (POS) banners so quality and longevity is guaranteed!
4D Number Plate Styles
4D number plate styles can range significantly. JDM Plates offer road legal 4D plates which consist of the following products in a range of legal sizes:-
There are so many other combinations available online; many of them are advertised as being fully legal when in fact they are not; beware of these suppliers!
Road legal number plate characters can only be black as stated in Schedule 2 of the ‘The Road Vehicles (Display of Registration Marks) Regulations 2001′. No other colour! Krystal number plates have the subjective exception as they are transparent and don’t technically have a colour. However, carbon 4D plates, coloured 4D plates and 4D plates with a black surface but colour backing are illegal; if you mount these number plates on your vehicle and are pulled over, you are very likely to receive an on the spot fine of £100.
What are the requirements for 4D Number Plates?
The legal requirements of 4D number plates are the same as that of every other road legal number plate. The relevant legislation still needs to be complied with in order to ensure the 4D registration plate is fully road legal. Some of the requirements for characters include:-
Character Height – 79mm / 64mm
Character Width – 50mm (14mm for 1 or I) / 44mm (10mm for 1 or I)
Character Stroke – 14mm / 10mm
Spacing between Characters – 11mm / 10mm
Spacing Between Groups (Horizontal) – 33mm / 30mm
Spacing Between Groups (Vertical) – 13mm / 5mm
Character Font – Charles Wright ONLY
Minimum Outer Margins – 11mm / 10mm
However, there are some other requirements that must be considered for imported vehicles with regards to the bottom plate margin and the vertical spacing between groups; they can be slightly different!
Not only do the sizes and spaces need to be complied with, but the materials need to meet a specific grade. For instance, the reflective material must meet a specific standard to ensure the minimum level of light is reflected. The black (only black) 4D characters must reflect a limited amount of lumens and the overall construction of the number plate must meet specific standards with regards to resistance of: temperature, abrasion, chemical splash, ultraviolet rays and discolouration. However, many BNMA suppliers will ensure their materials comply with all the material specifications; JDM Plates proudly only use BNMA registered suppliers for 4D number plate material.
